Hello!
It is metaphor
This is being compared between something that is not applicable.
It is not simile because it doesn't have the words 'like' or 'as'.
Not a hyperbole since it isn't an exaggeration.
Finally, it is not a personification because it does not compare a human like feature to an inanimate object.
Hope this helps! :D
B four examples is the answer
I put C on my test because it seem most logical plus I couldn't find much to help me.
I know right! Thanks for the points :D
